Can be used for slight performance upgrade on 46RE and 47RE applications.

Cores for Chrysler light-to-medium-duty trucks are scarce and often modified beyond repair. Patent-pending innovation allows Sonnax to convert plentiful early-model RE Chrysler cores to premium-quality 48REs.

  • 100% tested to ensure pressure curves and timing match 48RE OE design.
  • Great for pressure and lockup upgrades in 46/47RE.
  • Refurbished and improved with Sonnax parts.

Valve body part improvements include:

  • Sonnax manual valve
  • Sonnax oversized throttle valve kit
  • Sonnax valve body detent ball and sleeve kit
  • Sonnax oversized 4-spool switch valve
  • Sonnax oversized lube regulated PR valve and line/TV pressure plug kit
  • Patent-pending pressure curve components
  • Patent-pending lockup conversion components
  • 3-4 accumulator spring
  • New governor pressure solenoid
  • New governor pressure sensor

If using in a 46/47RE application, a triple-plate converter must be used.
